ruby-on-rails-3 - 没有路由匹配 :action => edit rails 3

Question

我不明白为什么在尝试更新菜谱时收到上述错误消息

这是我的 rake 路线的输出

      recipes GET    /recipes(.:format)                recipes#index
              POST   /recipes(.:format)                recipes#create
   new_recipe GET    /recipes/new(.:format)            recipes#new
  edit_recipe GET    /recipes/:id/edit(.:format)       recipes#edit
       recipe GET    /recipes/:id(.:format)            recipes#show
              PUT    /recipes/:id(.:format)            recipes#update
              DELETE /recipes/:id(.:format)            recipes#destroy
         root        /                                 public_pages#index

我的 Controller 看起来像这样

def edit
  @recipe = Recipe.find(params[:id])
end

def update
  @recipe = Recipe.find(params[:id])

  if @recipe.update_attributes(params[:recipe])
    redirect_to recipes_path, :notice => "Successfully updated recipe"
  else 
    render :action => 'edit'
  end
end

以及我编辑帖子的链接

<%= link_to "Edit Recipe", edit_recipe_path(@recipe) %>

完整的错误是(这是在尝试访问食谱页面时

Routing Error

No route matches {:action=>"edit", :controller=>"recipes"}

Try running rake routes for more information on available routes. 

最后是我正在使用的表单，现在我唯一能想到的是我的表单有问题，尽管我认为您可以使用相同的表单进行新建和编辑？虽然我可能完全错了

大家有什么想法

Answer 1

好吧，看来我需要这个

 <%= link_to "Edit Recipe", edit_recipe_path(r.id) %>

这是因为我通过了

 <% @recipes.each do |r| %>
